CS51021A
CS51021A is PWM Controller manufactured by onsemi.
Enhanced Current Mode PWM Controller
The CS51021A Fixed Frequency PWM Current Mode Controller provides all necessary Features required for AC- DC or DC- DC primary side control. Several Features are included eliminating the additional ponents needed to implement them externally. In addition to low startup current (75 mA) and high frequency operation capability, the CS51021A includes overvoltage and undervoltage monitoring, externally programmable dual threshold overcurrent protection, current sense leading edge blanking, current slope pensation, accurate duty cycle control and an externally available 5.0 V reference. The CS51021A Features bidirectional synchronization...
